Genesis 28:10

And Esau seeing that the daughters of Canaan pleased not Isaac his father;

Then went Esau unto Ishmael, and took unto the wives which he had Mahalath the daughter of Ishmael Abraham’s son, the sister of Nebajoth, to be his wife.

And he lighted upon a certain place, and tarried there all night, because the sun was set; and he took of the stones of that place, and put them for his pillows, and lay down in that place to sleep.

And he dreamed, and behold a ladder set up on the earth, and the top of it reached to heaven: and behold the angels of God ascending and descending on it.
